disk on key with pic's...

sweet_Dana · Guest

Hi

I would like to get any kind of information about reading a file from disk on key, with pic16f88 \pic16f69.

I want to read and write words or numbers from it.

Can I do it ? The information is stored in files? Or I can just write numbers to it ?
Is it the same as writing to a computer usb ? I guess not...

Any discussion about that or codes that could help me will be nice.

Do a search of this forum for 'thumb drive' or 'pen drive'. Simple answer is no, this is not realistic with small PICs because of USB architecture.

If you are referring to an USB memory stick, you should tell more clearly. "Disk on key" can mean a lot...

USB devices can be accessed only by an USB host or dual-role (OTG) controller. From Microchip, PIC24FxxGB series could do. CCS has no example code for it, but there are Microchip examples, including access to memory ("mass storage") devices. A FAT16 file system as with memory cards is used to organize the data storage.

Vinculum VNC1L does the job. Two USB ports, and with the right firmware one can attach to a host PC as well. You can get the VDIP1 or VDIP2 module, which makes the hardware part easier.
